[BNM] PHP. Any recommendations for running a php process asynchronously?

[AndrewGill73@gmail.com]

Thanks David and Leo.  I don't have any programming experience in a
multi-threaded language unfortunately.

Yes, I will re-engineer the process as David suggested. I will then
execute the php script from shell (probably using wget).

I need the xmpp process to be scalable so will execute the script
(using wget) on different hosts to get some scalability (if required).

Any other ideas / input very welcome!

cheers,
Andy
